Jason Derulo has his work cut out for him this weekend as he tries to cling on to that pole position one more time.

Jason Derulo held on to the No.1 spot for a THIRD consecutive week. The 'Talk Dirty' star will make it an incredible FOUR weeks at the top of the freshest chart in the world if he can hang onto the coveted position for just a little longer.

There are BIG releases from Britney Spears, Chris Brown AND Walk The Moon all threatening to knock Jason down a peg or two. Will Jason weather the storm? Well that's up to you guys.

Have a look at the tracks with a chance of bagging themselves the next No.1 single:
